39718787FFD3FFEBEF28FE5173DC6684.taxon	description	Description (based on male holotype andmale andfemalesparatypes; measurements in Table I). Coloration. – Prosoma: carapace yellowish (male) to brownish yellow (female) with diffuse variegated dark brown to blackish spots between lateral eyes and median ocular tubercle; eyes surrounded by black pigment. Mesosoma: tergites yellowish (male) to brownish yellow (female); sternites, coxapophysis, sternum and genital operculum yellowish, pectines pale yellow. Metasoma: yellowish with dark brown to blackish pigmentation on segment V. Vesicle pale yellow; aculeus reddish yellow at the base and reddish at its extremity. Chelicerae yellowish without any reticulation; teeth reddish. Pedipalps: yellowish, the rows of granules on the dentate margins of the fingers reddish. Legs pale yellow. Morphology. – Prosoma: anterior margin of carapace not emarginate, straight, bearing ten macrosetae. Carapace carinae weak; anterior median carinae obsolete; central median, posterior median and central lateral carinae weak. All furrows weak to obsolete. Intercarinal spaces moderately granular. Median ocular tubercle slightly anterior to the centre of the carapace; median eyes separated by about two ocular diameters. Five pairs of lateral eyes; the first four disposed in one line, the fifth situated behind fourth eye. Mesosoma: tergites I-VI tricarinate; all carinae weak; lateral carinae vestigial on segment I; tergite VII pentacarinate, with lateral pairs of carinae strong. Intercarinal spaces with fine granulation in central area of tergites, with coarse and fine granulation on lateral sides. Sternites smooth; all carinae absent from sternites III-VI; sternite VII with two pairs of smooth carinae. Pectines with the marginal tips extending to the end of sternite III in female, end of sternite IV in male; pectinal tooth count 15 - 17 in females, 22 - 24 in males; pectines with 3 marginal lamellae and 8 - 9 middle lamellae; lamellae and fulcra with numerous setae. Metasoma: segment I with 10 complete carinae, II-IV with 8 complete carinae (incomplete lateromedial carinae on posterior half of segment II, indicated by a few granules on posterior part of segment III), V with five carinae. Ventral carinae weak on segment I, with well-marked spiniform granules on II-III (especially in female), weak on IV; dorsal carinae without any well marked spinoid granules on segments I to IV. Segment V with ventral and ventrolateral armed with moderate to strong spinoid granules and several conspicuous spinoid lobes. Dorsal furrows of all segments weakly developed; dorsal and lateral intercarinal spaces smooth on all segments; ventral intercarinal spaces smooth on segments I-III, weakly granulated on IV-V. Segment V with 36 long setae. Anal arc composed of 6 ventral teeth and two lateral lobes. Telson smooth. Aculeus very long and curved; subaculear tubercle absent. Chelicerae with two reduced but not fused denticles at the base of the movable finger (Vachon, 1963). Pedipalps: Trichobothrial pattern orthobothriotaxic, type A (Vachon, 1974); chela fixed fingers with trichobothrium eb slightly displaced on chela manus, situated closer to Et than esb; trichobothrium db distal to esb; dorsal trichobothria of femur in β (beta) configuration (Vachon, 1975). Femur pentacarinate; all carinae moderately crenulate. Patella and chela with vestigial carinae only, almost smooth. Pedipalp chela manus strongly inflated in male; fingers straight in female, twisted in male, with 8 rows of granules on fixed finger, 9 on movable finger; each row with one external and one internal accessory granule, both moderate to strong; 3 terminalgranulesnexttotheterminaldenticle. Legs: Ventral aspect of tarsi with numerous thin long setae. Tibial spurs moderate on legs III-IV. Relationships. – Buthacus deserticus sp. n. shows similarities with regard to several morphological characters as well as a similar biotope, with B. spinatus and B. elmenia, both species belonging to the “ leptochelys ” complex and occurring in the region of Ghardaïa, Central Algeria. The new species can however be easily distinguished from these species notably by the following main features: (i) larger size with 44 - 52 mm (36 - 42 mm in B. spinatus, 41 mm in B. elmenia); (ii) general coloration yellowish to brownish yellow with darker pigmentation on carapace (yellow to pale yellowwithoutspots oncarapace in B. spinatus and B. elmenia); (iii) pectinal tooth count 22 - 24 in male (19 - 20 in male B. elmenia); (iv) ventral and latero-ventral carinae on segment V with moderate to strong spinoid granules and several conspicuous spinoid lobes (stronger granulation in B. spinatus, spinoid lobes inconspicuous in B. elmenia); (v) male pedipalp chela manus strongly inflated (moderately inflated in B. spinatus); (vi) chela fixed fingers with trichobothrium db distal to esb (at the same level in B. spinatus); (vii) vesicle more bulky in female and several other distinct morphometric values (Tab. I).	en	Sadine, Salah Eddine, Souilem, Zineb, Chedad, Abdelwahab, Chebihi, Bahri, Zebsa, Rabah, Houhamdi, Moussa, Lourenço, Wilson R., Ythier, Eric (2024): A new species of Buthacus Birula, 1908 from the Algerian Saharan Desert (Scorpiones: Buthidae).
